Authorities expressed concern earlier in the week as 25 cranes still stood in Miami during Irma.

Emergency personnel were unable to respond because of high winds, Miami-Dade County Director of Communications Mike Hernandez said. "The answer - it's a slow process that can take about TWO weeks and there is NOT enough time", they said. The building was still in tact despite the crane's failure. People also posted pictures of the cranes.

Officials urged people in buildings facing the crane to seek shelter on the opposite side of the building or in a stairwell. Although Miami will miss the worst of Irma's top winds of 130 miles per hour, the Miami has seen gusts of up to 100 miles per hour.

The arms of the tower cranes are left unlocked during storms, allowing them to swing around and follow the wind, much like a weather vane.

City officials said they were using geo-fencing, a 911 communication system, as well as social media, to contact residents in the area.
